Books by Tim Halliday

Professor Tim Halliday is an evolutionary biologist, primarily interested in amphibians. His initial focus was on the sexual behaviour of amphibians, but has become increasingly interested in their life histories and ecology. For the last twelve years he has led an international initiative to investigate why amphibians are in severe decline throughout the world. Tim has published numerous research publications, and has contributed materials to a number of previous Open University course texts. Dr Basiro Davey is Deputy Director of the Health Sciences programme at the Open University, and course chair for the Open University course for which this series has been developed. Basiro joined the Science Faculty of the Open University in 1976, having previously been a researcher investigating various aspects of tumour immunology. Since then, she has been a major contributor to many Open University courses, including Health and Disease, Human Biology and Health, and Infectious Disease. An experienced textbook author, Basiro has originated much published course material during her time at the Open University; she continues to be series editor for the nine-text Health and Disease series, which is cop-published with the Open University Press.
